Flatten a source of sources by emitting their contents in series
Streams are concatenated in order -- note that this means they need to not be
infinite if any subsequent streams are to be processed! The output is closed
when all sources are finished or if any source throws (in which case the
error propagates to the subscriber).
If you want to switch to a new stream whenever a new source arrives from the
input stream, use switchAll instead.
